In at least some implementations, a window assembly for a motor vehicle includes a guide rail having at least one wall that defines at least part of a guide track, a movable pane associated with the guide rail and movable relative to the guide track along a path of movement defined by and between a closed position and a fully open position, and a retainer. The retainer may be coupled to the movable pane and be movable with the movable pane, and be located at least partially within the guide track. The retainer may further include at least one biasing member that is engaged with the wall along the path of movement to limit movement of the retainer relative to the guide rail.

The present invention provides an annular roller device for a sliding window/door, which is proposed as a roller device having a new structure wherein the roller device installed under a door sash can move a sliding window/door having heavy weight, and can maximize the open glass portion of the window/door by minimizing the height of the space required to install the roller device, thereby providing a more open view. The roller device has a structure in which, even when a rail installed on a window frame is not horizontal or the bottom portion of a window is not completely flat, all multiple rolling members, which constitute a ring-shaped rolling unit wound around a load-bearing plate (1220) comprising segment bodies (1221, 1222) rotatably connected to each other by a pivot pin (1225) extending therethrough, form contact points with the rail or the bottom portion, and thus each of the rolling members is prevented from being loaded with excessive weight.

A door open and close mechanism for opening and closing a plurality of doors in a machine tool including a cover. The door open and close mechanism includes a linkage mechanism and a slide mechanism. The linkage mechanism is disposed between an operation door and an intermediate door. The linkage mechanism associates the intermediate door with the opening and closing of the operation door. The slide mechanism is disposed between the operation door and the linkage mechanism. The slide mechanism enables the operation door alone to open and close by a predetermined moving distance. When the operation door is operated to open and close within the moving distance, the operation door alone opens and closes by the slide mechanism When the operation door is operated to open and close beyond the moving distance, the intermediate door opens and closes in association through the linkage mechanism.

A frame includes sliding panels to cover an opening of a cabinet. The panels are mounted to interlocking stiffeners. Each of the interlocking stiffeners includes a base portion that forms a channel to receive a forward leading edge or a rear leading edge of the panels. The interlocking stiffeners share forces between the panels. A latch assembly may also be engaged to the interlocking stiffener attached to the forward leading edge of the panel. The latch assembly includes a protruding or projecting portion, such as a bullnose, that positions the latch assembly with respect to a side frame member. During a closing operation, the protruding portion enters a channel of the side frame member. The protruding portion engages with the channel of the side frame member, which results in proper alignment for the latch assembly.

A sliding door assembly includes a door frame with a top trim member, a bottom sill, and side jambs connected between the top trim member and the bottom sill, and a primary sliding panel secured in the door frame. The top trim member includes a track configured to support a weight of the primary sliding panel and prevent the primary sliding panel from coming off the track. Other features include an interlock mechanism to limit relative movement using multiple sliding doors and a brake mechanism to secure the doors in position when the door handle is released. A drop window includes features to accommodate for manufacturing tolerances and box frame assemblies that are out of square.
